so , if radius is 99 just multiply it with 2

99 x 2 = 198

Answer 2

Answer:

Diameter of circle is 198 cm .

Step-by-step explanation:

Given information,

Radius of circle is 99 cm.

We have to find out the value of The diameter of a circle.

Diameter is a straight line from one side to the other side that passes through the center point of a circle.

Radius is half of diameter .

As we know that ,

Radius is half of diameter.

Radius = Diameter ÷ 2

Diameter = Radius × 2

As per the given data ,

Diameter = 99 × 2

By dividing by 2 we get

Radius = 198

Hence,

Diameter of circle is 198 cm .
